Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. The components of the embodiments of the present disclosure, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present disclosure, presented in the figures, is not intended to limit the scope of the claimed disclosure, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Network devices (e.g., switches) are generally classified into centralized devices and distributed devices according to physical modalities. The centralized equipment is also called as box type equipment, the whole box type equipment only has one single board, and the single board is a single board integrating a main control board and an interface board. While distributed devices (also known as boxed devices), with a height of 2U (about 8.89cm) and above, the control plane and data plane are physically separated. The distributed equipment generally comprises a case, a main control board, an interface board and a screen board. The main control board is responsible for controlling the plane, and can be generally divided into a main control board and a standby control board according to actual roles, and the main control board and the standby control board are redundant backups of each other. The interface board and the network board are responsible for a data plane, the network board is responsible for forwarding cross-board traffic between different interface boards, the interface board usually comprises a service interface, and the network board usually does not have any service interface.
In detail, referring to fig. 1, taking an example that the interface board includes a first interface board and a second interface board, each interface board generally includes one or more switch chips. For example, in the application scenario shown in fig. 1, the first interface board includes a switch chip a, a switch chip b, a switch chip c, a switch chip d, and the like, respectively, and the second interface board includes a switch chip e, a switch chip f, and the like, respectively. These switching chips may have table lookup forwarding capability for messages. The mesh board generally includes one or more mesh sheets, and the mesh sheets may directly forward the packet according to internal header information (e.g., a destination address) of the packet sent by the first interface board or the second interface board, and forward the packet to an interconnection port of the switching chip where the packet output port is located. For example, in the application scenario shown in fig. 1, if the internal header information of the message received by the mesh 2 in the mesh B from the switch chip a of the first interface board indicates that the message needs to be sent to the switch chip f of the second interface board, the interconnection port of the switch chip f where the message output port is located is searched through a preset forwarding table entry, and then the message is sent to the switch chip f through the interconnection port.
In the application scenario shown in fig. 1, the network sheets are not connected to each other, and the switching chips are also not connected to each other, and each network sheet needs to be connected to all the switching chips of the first interface board and the second interface board. It should be noted that fig. 1 only shows the case where the mesh 2 and the mesh 3 in the mesh panel B are connected to all the switch chips, and for other mesh panels, for example, the mesh panel a, the mesh panel C, and the mesh panel D can be connected to all the switch chips of the first interface board and the second interface board with reference to the scenario shown in fig. 1.
As mentioned in the background art, each mesh generally can participate in message forwarding only by setting a message forwarding table entry, and only when a network device is accessed for the first time or a subsequent mesh or interface board is changed, a processor and a memory are needed. However, the inventor finds that in the actual use process, the situation that a processor and a memory are needed is less, if the processor and the memory are arranged in each network board, unnecessary cost is inevitably increased, which leads to cost performance reduction of network equipment, and if the network board can normally participate in the message forwarding process without designing the processor and the memory, the cost is greatly reduced.
For this reason, based on the findings of the above technical problems, the present inventors propose the following technical solutions to solve or improve the above problems. It should be noted that the above prior art solutions have shortcomings, which are the results of practical and careful study by the inventor, and therefore, the discovery process of the above problems and the solutions proposed by the embodiments of the present disclosure in the following description should be the contribution of the inventor to the present disclosure in the process of invention creation.
Referring to fig. 2, the embodiment of the disclosure uses a web panel 130 without a processor and a memory to provide a low-cost network device 100. As shown in fig. 2, the network device 100 may include a first main control board 110, a second main control board 120, and a network board 130 connected to the first main control board 110 and the second main control board 120, respectively. In addition, the network device 100 further includes a first interface board 140 and a second interface board 150, and the first main control board 110 and the second main control board 120 are respectively connected to the first interface board 140 and the second interface board 150. The first interface board 140 and the second interface board 150 may include at least one switch chip 160, each switch chip 160 is connected to each mesh 132 in the network board 130, and reference may be made to the above description for fig. 1 regarding specific connection relationships of the mesh 132 and the switch chip 160.
The first and second host boards 110 and 120 may include a Central Processing Unit (CPU) 102, a Peripheral Component Interconnect Express (PCIE) chip 104, and an Inter-Process Communication (IPC) chip 106, and each of the network boards 130 may include a network 132 and a PCIE interface 134 connected to the network 132. The PCIE chips 104 of the first main control board 110 and the second main control board 120 are respectively connected to the PCIE interface 134 of each network board 130. The IPC chips 106 of the first main control board 110 and the second main control board 120 are connected to the first interface board 140 and the second interface board 150, respectively, and the PCIE chip 104 and the IPC chip 106 are connected to the CPU102, respectively. In this way, the CPU102 of the first main control board 110 or the second main control board 120 can control and manage the mesh 132 of each network board 130 through the PCIE chip 104, and can control and manage the first interface board 140 and the second interface board 150 through the IPC chip 106. Through the above design, each screen 130 does not separately set a processor and a memory to control and manage the mesh 132, but directly controls and manages the mesh 132 through the first main control board 110 or the second main control board 120.
The network device control method shown in fig. 3, which is performed by the network device 100 shown in fig. 2, is explained in detail below with reference to fig. 2. It should be understood that, in other embodiments, the order of some steps in the network device control method of this embodiment may be interchanged according to actual needs, or some steps may be omitted or deleted. The detailed steps of the network device control method are described below.
Step S110, when the network board 130 is first accessed to the network device 100 and is in the first control state controlled by the first main control board 110, the first main control board 110 performs initialization configuration on the network board 130, and after the initialization configuration is finished, the network board 130 is isolated so that the network board 130 does not participate in message forwarding.
Since there is no processor or memory in the web 130, the network device 100 will view it as a light panel. The optical board is a logical single board, and can be understood as a software program that needs to be run by being attached to the first main control board 110 or the second main control board 120. In this embodiment, one of the first main control board 110 and the second main control board 120 serves as an active main control board of the network device 100, and the other serves as a standby main control board. In detail, taking the first main control board 110 as an active main control board and the second main control board 120 as a standby main control board as an example, when any network board 130 is accessed to the network device 100, a diskless boot ROM interface (also called Bootrom) on the network board 130 sets a PCIE configuration register of each mesh 132 in the network board 130, so that each mesh 132 and the first main control board 110 are in an effective connection state, and thus the network board 130 is in a first control state controlled by the first main control board 110.
The Bootrom is a boot program of the network device 100 (e.g., the network device 100 such as an ethernet switch or a router), and the Bootrom may start running at a designated location in the network board 130 and is responsible for booting the network board system. For example, the PCIE configuration register of each mesh 132 may be configured through Bootrom, so as to control the connection state between the PCIE interface 134 of the mesh 132 and the first main control board 110 or the second main control board 120 to be an effective connection state or an invalid connection state. For example, if the connection state between the PCIE interface 134 of the mesh 132 and the first main control board 110 is an effective connection state, the mesh 132 may be controlled by the first main control board 110; if the connection state between the PCIE interface 134 of the mesh 132 and the second main control board 120 is an effective connection state, the mesh 132 may be controlled by the second main control board 120.
When the screen 130 is in the first control state, the first master control board 110 starts to perform initial configuration on the software table entry and the hardware table entry of each mesh 132 in the screen 130. The software table entry of the mesh 132 may include, but is not limited to, software parameters, running program modules, running data, and the like of the mesh 132, and the hardware table entry of the mesh 132 may include, but is not limited to, chip hardware parameters of the mesh 132, port parameters of each port on the mesh 132, and the like. Taking the screen 130 as the screen B shown in fig. 1 as an example, when the screen B is in the first control state, the first main control board 110 starts to perform initialization configuration on the software table entries and the hardware table entries of the mesh 2 and the mesh 3 in the screen B.
Meanwhile, the first main control board 110 may further set a forwarding table entry of each mesh 132 in the mesh 130 according to a connection relationship between each mesh 132 in the mesh 130 and each switch chip 160 in the first interface board 140 and the second interface board 150 and a chip identifier of each switch chip 160 in the first interface board 140 and the second interface board 150, and set the forwarding table entry in a software table entry and a hardware table entry of each mesh 132 after the initialization configuration. For example, as shown in fig. 2, the CPU102 of the first main control board 110 may obtain, through the PCIE chip 104 and the IPC chip 106, a connection relationship between each mesh 132 and each switch chip 160 in the first interface board 140 and the second interface board 150 and a chip identifier of each switch chip 160 in the first interface board 140 and the second interface board 150, so as to obtain an interconnection port number of an interconnection port where an output port of each mesh 132 is connected to each switch chip 160, and a chip identifier of the switch chip 160 where each interconnection port number is located. Then, a corresponding relationship between the outgoing port number and the interconnection port number of each mesh 132 and the chip identifier of the switch chip 160 is established, a forwarding table entry of each mesh 132 can be set according to the corresponding relationship, and the forwarding table entry is set in the software table entry and the hardware table entry of each mesh 132 after the initialization configuration.
Through the design, the initialization configuration of the network board 130 can be completed, and the network board 130 can participate in normal message forwarding because the network board 130 is already configured with software table entries and hardware table entries.
The inventor found that the screen 130 can be controlled by only one main control board at the same time, and after the initialization configuration of the screen 130 is completed by the first main control board 110, the initialization configuration of the screen 130 by the second main control board 120 needs to be carried out for a period of time. In order to avoid that the software table entry changes due to the network board 130 participates in message forwarding in the process of initializing and configuring the network board 130 by the second master control board 120, which is not beneficial to the subsequent software table entry synchronization between the first master control board 110 and the second master control board 120, the first master control board 110 also needs to isolate the network board 130 after initializing and configuring the network board 130 so that the network board 130 does not participate in message forwarding.
In a possible implementation manner, the way that the first master control board 110 isolates the network board 130 so that the network board 130 does not participate in message forwarding may be: the first interface board 140 and the second interface board 150 are configured with an aggregation group, where the aggregation group includes an interconnection port number that allows the first interface board 140 and the second interface board 150 to receive and transmit packets. When the first main control board 110 needs to isolate the network board 130, the first interface board 140 and the second interface board 150 may be controlled to delete the interconnection port numbers connected to each of the network boards 132 in the network board 130 in the aggregation group, so that the first interface board 140 and the second interface board 150 do not send messages to each of the network boards 132 in the network board 130 any longer, and do not receive messages from each of the network boards 132 in the network board 130 any longer, thereby isolating the network board 130 from the first interface board 140 and the second interface board 150.
Still taking the screen 130 as the screen B shown in fig. 1 as an example, the first main control board 110 may control the first interface board 140 and the second interface board 150 to delete the interconnection port numbers connected to the mesh 2 and the mesh 3 in the aggregation group, so that the first interface board 140 and the second interface board 150 do not send messages to the mesh 2 and the mesh 3 any more, and do not receive messages from the mesh 2 and the mesh 3 any more.
In step S120, the first main control board 110 saves the software entry file of the screen board 130 after the initialization configuration is finished and sends the software entry file to the second main control board 120, and switches the screen board 130 to a second control state controlled by the second main control board 120.
In detail, after the first main control board 110 isolates the screen 130 from the first interface board 140 and the second interface board 150, the software table entry file of the screen 130 after the initialization configuration is finished is stored and sent to the second main control board 120, that is, the standby main control board. Then, the screen board 130 is switched to a second control state controlled by the second main control board 120, for example, a PCIE configuration register of each mesh 132 in the screen board 130 may be set, so that each mesh 132 is in an effective connection state with the second main control board 120, and the screen board 130 is in the second control state controlled by the second main control board 120. When the screen 130 is switched to the second control state, the first main control board 110 may notify the second main control board 120 to perform the initialization configuration on the screen 130.
In step S130, the second main control board 120 performs initialization configuration on the screen board 130 according to the software entry file in the hot start state, and switches the screen board 130 to the first control state after the initialization configuration is finished.
Since the second main control board 120 is a standby main control board, and the network board 130 is mostly controlled and managed by the first main control board 110 as an active main control board, the hardware table entries of the network board 130 can only be configured and modified by the active main control board. If the hardware entries of the network board 130 are modified by both the first host board 110 and the second host board 120, the network board 130 may malfunction.
In order to avoid the foregoing problem, in this embodiment, the second main control board 120 may perform initialization configuration on the web board 130 according to the software entry file in the hot Boot state norm Boot. The norm Boot means that the Boot is controlled by software to restart without turning off the power supply, so that the hardware configuration can be skipped. Therefore, the hardware table entry of the screen 130 is not changed when the second main control board 120 is in a hot start state, so that when the screen 130 is initially configured, only the software table entry of the screen 130 needs to be configured according to the software table entry file sent by the first main control board 110, and the hardware table entry of the screen 130 does not need to be configured, thereby avoiding the fault of the screen 130 caused by the error modification of the hardware table entry of the screen 130.
On the basis, after the second main control board 120 completes the initial configuration of the network board 130, the control right of the network board 130 needs to be switched to the first main control board 110 as the main control board, but normally, the related task currently running by the second main control board 120 needs to continuously access the chip hardware of the network board 130. In order to avoid the subsequent abnormality of the operation of the network board 130 caused by the second master board 120 accessing the hardware of the network board 130 during the management control of the network board 130 by the first master board 110, as a possible implementation, the second master board 120 may set the currently running task to an idle state to suspend the execution of the currently running task.
After the task currently running is set to the idle state, the second main control board 120 switches the screen 130 to the first control state. For example, the PCIE configuration register of each mesh 132 in the network board 130 may be set, so that each mesh 132 is in an active connection state with the first main control board 110, and thus the network board 130 is in a second control state controlled by the first main control board 110.
In step S140, when the network board 130 is switched to the first control state, the first main control board 110 cancels the isolation of the network board 130 so that the network board 130 participates in the message forwarding.
When the network board 130 is switched to the first control state, the network board 130 is managed and controlled by the first main control board 110 and can normally participate in message forwarding. Based on the foregoing description, at this time, the network board 130 is still in an isolated state with the first interface board 140 and the second interface board 150, and therefore the first main control board 110 needs to cancel the isolation of the network board 130 so that the network board 130 can participate in message forwarding normally. For example, the first main control board 110 may control the first interface board 140 and the second interface board 150 to recover the interconnection port numbers, which are deleted from the aggregation group and connected to each mesh 132 in the mesh panel 130, so that the first interface board 140 and the second interface board 150 may send a message to each mesh 132 in the mesh panel 130, or receive a message from each mesh 132 in the mesh panel 130, so that the mesh panel 130 may participate in message forwarding.
Based on the above design, the initialization configuration process that needs the participation of the processor and the memory in the prior art is implemented by the first main control board 110 and the second main control board 120, so that the network board 130 can normally participate in the message forwarding process without setting the processor and the memory, thereby greatly reducing the cost of the network device 100 and improving the competitiveness of the product.
Optionally, in the process of managing the control screen 130 by the first main control board 110, when the states of the interconnection ports between the screen 130 and the first interface board 140 and/or the second interface board 150 change, or when the first interface board 140 and/or the second interface board 150 are plugged in or pulled out, or when the stacking topology of the network device 100 changes, the forwarding table entries on the related meshes 132 on the screen 130 need to be updated. However, since the network board 130 has no processor and no memory, the change of the forwarding table entry needs to be updated by the first main control board 110 and the second main control board 120 to ensure the normal message forwarding function of the network board 130. Therefore, with reference to fig. 4, after the step S140, the method for controlling a network device according to this embodiment may further include the following steps:
in step S150, when detecting that the screen board 130 has an entry change event, the first main control board 110 updates the software entry and the hardware entry of the target mesh 132 associated with the entry change event in the screen board 130 according to the detected entry change event.
Step S160, sending the updated software table entry to the second main control board 120, and switching the screen 130 to the second control state.
In step S170, the second main control board 120 updates the software table entry of the target mesh 132 according to the updated software table entry in the hot start state.
Optionally, the entry change event may be, but is not limited to, an event that forwarding entries on the related mesh 132 on the mesh 130 need to be updated, which may be caused by any event, such as a change in the number of interconnection ports between the mesh 130 and the first interface board 140 and/or the second interface board 150, or a change in the stacking topology of the network device 100, and the like, which is not limited in this embodiment.
The first main control board 110 serves as an active main control board, and in the process of managing the control network boards 130, when it is detected that any network board 130 has an entry change event, the software entries and the hardware entries of the target mesh 132 associated with the entry change event in the network board 130 may be updated according to the detected entry change event.
Still taking the screen board 130 with the table entry change event as the screen board B shown in fig. 1 as an example, if the first main control board 110 detects that the interconnection ports of the mesh sheets 2 and 3 in the screen board B and the first interface board 140 change, the software table entries and the hardware table entries of the mesh sheets 2 and 3 may be updated according to the connection relationships between the mesh sheets 2 and 3 and the changed interconnection ports of the first interface board 140. Then, the updated software table entry may be sent to the second main control board 120, and the mesh 2 and the mesh 3 may be set to the second control state, at this time, the second main control board 120 may update the software table entries of the mesh 2 and the mesh 3 according to the updated software table entry in the hot start state.
Thus, when there is an entry change event in the network board 130, the processing flow of the entry change event that needs a processor and a memory to participate in the prior art is implemented by the first main control board 110 and the second main control board 120, so as to further ensure that the network board 130 normally participates in the message forwarding flow function.
Optionally, when the first main control board 110 has a main/standby switching event (e.g., a failure, a restart, a replacement, an inter-cut change, etc.), the first main control board 110 cannot perform management control on the network board 130 any more. In this case, in order to ensure that the network board 130 without the processor and the memory can continuously and normally operate, please further refer to fig. 5, after the step S140, the method for controlling the network device provided in this embodiment may further include the following steps:
in step S180, the network board 130 switches to the second control state when detecting that the main/standby switching event exists in the first main control board 110.
In step S190, the second main control board 120 cancels the hot start state and manages and controls the screen 130.
When the network board 130 detects that any active/standby switching event such as the aforementioned failure, restart, replacement, inter-cut change, etc., exists in the first main control board 110, the PCIE configuration register of each mesh 132 in the network board 130 may be set through the boost, so that each mesh 132 and the second main control board 120 are in an effective connection state, and thus, the network board is switched to the second control state. In the second control state, the second main control board 120 as the standby main control board is changed to the new active main control board for each mesh 132, and the idle state of the task that was running before the completion is canceled from the warm start state, and management control of the mesh board 130 is started.
